They also are quicker to drop the oldest versions of iOS, like iOS 8

For iOS, Germany and the US are always at the top (with Great Britain coming in third)

Three countries’ iOS developers stand above the rest when it comes to iOS 11 adoption, Realm adoption, and speed in dropping of old iOS versions. And Great Britain — despite coming in 12th for total builders — gets kudos for consistently finishing just behind Germany and the US.

Since Google I/O 2017, Kotlin’s rate of growth has jumped dramatically all over the globe

Kotlin rising

It’s clear: Java (on Android) is dying. There aren’t simply more Kotlin builders: they’re also switching their apps to Kotlin. In fact, 20% of apps built with Java before Google I/O are now being built in Kotlin. Kotlin may even change how Java is used on the server, too.

In short, Android developers without Kotlin skills are at risk of being seen as dinosaurs very soon.

Realm is the mobile world’s most popular third-party data technology. With an open-source core, and out-of-the-box features like realtime synchronization, offline-first support, and easy bridging to existing APIs and databases, it can help you make your apps faster and better.
